To all 'whom/t may concern: 1 y

Be it known that l, Nans lder, a citizen ff of the United States of America, and-resiments in Deep-Sea Rafts,

4A 4further object is the timber by water.

y The principal object of my invention is to provide means whereby logs may be con-r nected in rafts and towed at sea in such a way that the danger of the raftvbreaking up in heavy weather isgreatly minimized.

' which requires no specially built wharf or cradle, and which may be built in water only deep enough to float the logs.

A further object is the provision of a raft which is simple and cheaply constructed,

l and the metal securing parts of which may be used again.

A further object is the provision of a raft which in case of necessity may pass through a narrow channel.

My invention comprises the novel arrangement of parts which is shown in the accompanying drawing, which will be described in the present specication and particularly defined by the claims terminating the same.

ln the accompanying drawing my invention is shown in its present preferred arrangement.

rlhedrawing shows a plan view of a raft constructed according to my invention.

Along the Pacific coast there are many places where large trees grow near the waters edge and which may be profitably used except for the difficulty of transporting them to the mills. By means of my raft these trees can be dragged a short distance to the water and the whole tree, or as much thereof as can be used-for lumber, can be floated. lf a raft can -be constructed of these logs without special apparatus, which is expensive and difficult to transport, or special wharves or cradles, which are din cult to build in such remote territories as thetimber is to be found, the timber can be protably transported to the mills. However, there is often danger of a log raft being broken by heavy weather, particularly if all parts are rigid. It has been my object, therefore, to make my raft as flexiprovision of a raftA l lble as possible' while yet securingthecomponent logs securely together.

The 'various'logs'l which form-theindi vidual parts of my-raft--are varranged in sections, each Asection being vplacedimmediately behind the section "next preceding it..

The logs inv each sectionare exibly-secured together, `and to this end ll haveshow-n each lo e as transversely g bored at its .forward end,

tis-,indicated at 2, and through thisibore I pass a cable 3. The ends-of this cable may be united to forma towing bridle,` .clamps being employed for this purpose.

The various sections must be flexibly vsecured together and yet. the-logs must be I*confined sorthat they will not spread, particularly if stoppedinbpenwater. have --ltherefore, shown one .ormore ofthe; outermost logs l in each section as being transversely bored at its rear end and as indicated at 4c. If desired the cable forming the towing bridle 3 of a rear section may be passed directly through the bores 4 in the outer logs of the next section forward. ljreferably, but not necessarily, these outer logs 1 are somewhat longer than the inner logs 1 and thus one bight of the cable 3 is left free of the inner logs. These inner logs 1 are then free to move up and down, but are confined against spreading by the spaced and connected outer logs l. lt will be understood that a tow line 6 will be connected to the forward bridle 3 insteadof connecting this bridleto any forward section. y

The last section may be constructed as described above, except that it is preferable to pass one bight of a cable 7 over all of the logs .in the section, thence through the bores t at the rear ends of the outermost logs, and thence beneath all of the logs in this section. ln this manner all ofthe rear ends and connected together, however flexibly, but are prevented from being displaced relative to each other by following seas or section, except perhaps the outside logs 1,

are free to .move relative to each other exd cept as they are confined to a vertical motion by the outer logs l. tions are also flexible with respect to each other. ln passing through a narrow channel, if necessary the outside logs may be crowded in at their rear ends to lie upon The various seceach other to permit passage through such channel.

l have vshown 'the majority of the logs in each section as having their smaller ends forward and their butt ends to the rear. This should not be universallyr the case, however, as some of the logs should. have their butt ends forward to balance the section somewhat. At the saine time, it is desirable that the forward end of each section should be somewhat less in breadth than the rear end of the section next in advance thereof. Thus if the forward section can pass through a channel the forward end of the following section will follow the first section and will not strike upon any obstructions to tie upv the raft.

W hat l claim as my invention is:

1. A deepesea raft comprising a plurality of sections of floating logs, the logs in each.

section extending longitudinally, all of the logs in a section being flexibly connected at their forward ends, and the outermost logs only being flexibly connected at their rear ends to the following section.

2. A. deep-sea raft comprising a plurality nadas/io nect with the rear ends of the' outer logs onl i of the section next in advance thereof.

deep-searraft comprising a plurality of sections of longitudinally-extending oating logs, the forward ends of all of the logs of a section and the rear ends of the outer logs of a section being bored., and a single cable passing through the 'bores at the forward ends of all logs in a given section, and pass ing also through the bores in the rear ends of the outer logs in the next section in advance thereof, and means connecting together the ends of said cable.

4f. A deep-sea raft as inclairn 3, the out errnost logs of a forward section being longer than the intermediate logs thereof, whereby the cable is clear of the intermediate logs.
